THE latest movie about ­Princess Diana’s life will be based on her bodyguard’s ­memoirs, it emerged yesterday.

BAFTA-winning British film ­producer Stephen Evans wants to show the world “the real Diana” and is lining up a Hollywood actress to play the princess.

The £30million film, out next year, will be told from the point of view of bodyguard Ken Wharfe and is based on his controversial 2007 book Diana: Closely Guarded Secret.

Evans has also been working with Diana’s private secretary Commander Patrick Jephson.

The plot will follow the years leading up to Diana’s divorce from Prince Charles in 1996.

But it will not cover her ­relationship with Dodi Fayed or theories about her death in a 1997 car crash. Evans said: “We are dealing with about 11 years of her life from after she had Harry, when he’s aged about two, and it’s partly from the point of view of her protection bodyguard.

“The emphasis of this really is authenticity and to discover what she went through.

“Unless you are a Diana freak, quite a lot of it will be unknown to the audience. The movie’s not saying she is unbelievably ­wonderful or she’s a pain in the neck, the audience can make their own view.”

The success of Margaret Thatcher biopic The Iron Lady has prompted moguls to dust off Diana scripts in Hollywood.

Actresses rumoured to portray Diana include ­Charlize Theron, 36, and Carey Mulligan, 26, with Ewan ­McGregor, 40, lined up to play Wharfe.

Evans would not ­reveal who is currently favourite to play the ­princess, saying: “It’s a ­slightly closed book until we get her.”

Meanwhile, two other Diana ­biopics are in pre-production.

­Scarlett Johansson, 27, and Keira Knightley, 26, are rumoured to appear in a Pathé film called Diana.

And Jessica Chastain, 30, is set to star in Caught in Flight, which details Diana’s relationship with heart surgeon Hasnat Khan.
